Katie has a coin collection she keeps 7 of the coing in the box which is only 14% of her entire collection. What is the total nu
mr Goodwill [35]

Answer:

x= 50

Step-by-step explanation:

7/x = 14/100

14x = 700

x = 50

the reason behind my calculations were to get the same ratios and because they gave us percentage and the actual number, we can set them; 14 percent 14/100, however, the 7/x is because we don't know the 100 percent of the coins which is what we look for. Therefore, you cross multiply and get x.

I hope this helped

How do I solve this 9x-(x-24)=2x-(-5+x)
Viefleur [7K]
Combine like terms
8x+24=x+5
subtract x from both sides

8x+24=x+5
-x -x
7x+24=5
subtract 24 from both sides
7x+24=5
-24 -24
7x = -19
divide 7 from both sides
7x = -19
7x/7 = -19/7

x= -19/7

The quadrilateral ABCD has area of 58 in2 and diagonal AC = 14.5 in. Find the length of diagonal BD if AC ⊥ BD.
MAXImum [283]
We know that

<span>The formula for the area of a quadrilateral with perpendicular diagonals is
</span>A=(0.5)*(D1*D2)
A=58 in²
D1=AC=14.5 in
D2=BD=?

so

D2=2*A/D1-----------> 2*58/14.5-----------> D2=8 in
BD=D2=8 in

the answer is
BD=8 in
